0.5m-3.5=3.2m+7
Use the distributive property to multiply 2 by 1.6m+3.5.
0.5m-3.5-3.2m=7
Subtract 3.2m from both sides.
-2.7m-3.5=7
Combine 0.5m and -3.2m to get -2.7m.
-2.7m=7+3.5
Add 3.5 to both sides.
-2.7m=10.5
Add 7 and 3.5 to get 10.5.
m=\frac{10.5}{-2.7}
Divide both sides by -2.7.
m=\frac{105}{-27}
Expand \frac{10.5}{-2.7} by multiplying both numerator and the denominator by 10.
m=-\frac{35}{9}
Reduce the fraction \frac{105}{-27} to lowest terms by extracting and canceling out 3.
